摘要： A fixing device includes a hollow cylindrical sleeve provided to surround a hollow glass roller containing a halogen heater therein, and a pressure roller that contacts and presses the glass roller and the sleeve. The glass roller is made of an infrared-transparent material. The sleeve has an inner diameter larger than the outer diameter of the glass roller and it is heated by absorbing infrared rays from the halogen heater. The pressure roller nips and holds the sheet carrying the toner between itself and the glass roller and as the sleeve.

摘要： An image fixing apparatus is formed by a fixing roller which contacts an image surface of a recording mediums and performs fixing, a pressure roller which is urged against the fixing roller to thereby apply a necessary pressure needed for fixing of a toner image upon the recording medium, and an external heating roller which has an internal heat surface and when urged against the fixing roller, keeps a surface layer of the fixing roller at a predetermined temperature which is necessary for fixing. A heat transfer coefficient of the fixing roller is 20 W/m2·K to 100 W/m2·K. This guarantees a necessary fixing nip width which is needed for fixing of images without increasing the size of the apparatus or remarkably increasing a holding pressure at the fixing nip portion. Further, it is possible to stably maintain an appropriate fixing temperature without increasing the temperature gradient of the surface layer portion for adding a filler material to the surface layer. In an image forming apparatus using such an image fixing apparatus, stable and high-quality fixing of images one at a time not to mention, but also even continuously is realized.
摘要翻译：图像定影设备由与记录介质的图像表面接触并执行定影的定影辊形成，压力辊被推靠在定影辊上，从而将调色剂图像定影到记录介质上所需的压力以及具有内部热表面并且当被推靠在定影辊上时的外部加热辊将定影辊的表面层保持在固定所需的预定温度。定影辊的传热系数为20W / m2.K至100W / m2.K。这确保了在不增加设备尺寸或显着增加定影夹持部分处的保持压力的情况下固定图像所需的固定夹紧宽度。此外，可以稳定地保持适当的定影温度，而不增加用于向表面层添加填充材料的表面层部分的温度梯度。在使用这种图像定影装置的图像形成装置中，可以一次一个地稳定且高质量地固定图像，甚至连续地实现。
